BALlNG-PRESS.

SPECIFICATION formingpart of Letters Patent No. 249,908, dated November 22, 1881.

Application filcd August 23, 1881. (No model.)

To all whom it may concern Be it known that we, J osErH PAUL DEAN and DANIEL J. MARTIN, both of the city and county of New York, in the State of New York,

have invented certain new and useful Improveing different materials, especially cotton, which is so constructed that the principal parts may be made of wood, and may,therefore, be quickly and cheaply repaired or replaced, when broken, in any locality where timber is plenty, also,

to give a comparatively quick motion of the press-follower at the beginning of its movement and when there is the least resistance, and a slower motion as it approaches the end of its movement and when there is the greatest resistance.

The invention consists in the combination, with a press-follower, ot'a cam pivoted thereto, a bearing-roller mounted in stationary bearings below said follower, and a cord or other flexible connection attached directly to said cam for drawing it upon and over said bearingroller, and thereby raising the press-follower, as hereinafter described and claimed.

It also consists in the combination, with said 3 follower, a cam, and bearing-roller, of a pressbox, in the sides ofwhich are openings through which the cam works, and which are closed by doors that are opened by the cam as it moves inward toward the center of the press to raise 3 5 the follower, and are automatically closed as the cam moves outward.

It also consists in the combination, with a press-follower, a cam pivoted therein, a bearing-roller below said follower, and means for 40 operating said cam, ofa press-box, in the upper part of which are doors through which the bales are removed, catches for holding said doors closed, and mechanism upon which the cam acts at the completion of its movement to release said catches automatically and allow 4 the doors to be opened.

It also consists in various details of construction and combinationsof parts to be hereinafterdescribed, and pointed out in the claims.

In the accompanying drawin gs,Figure 1 represents a central verticalsection of our improved press; Fig. 2, a plan thereof with the head thereof removed; and Fig. 3 represents a transverse vertical section of the press-follower, and an edge view of the cam and bearing-rollers.

Similar letters of reference designate corresponding parts in all the figures.

The frame-work of the press, which is entirel y of timber, comprises four corner-posts,A,

which maybe of any suitable sizesay twelve inches squareand cross-beams A, by which thecorner-posts are connected together. Within this frame-work is secured the press-box B, which is composed of plank and contains the vertically-movable follower. The said follower is composed of two timbers or side pieces, 0, and pieces a, connecting them together at the top, and allowing spaces through which the bale-bands may be inserted. The top of the press-box B is closed by a head, D, which is rabbeted at opposite ends, as seen in Fig. 1, and is adapted to be slid into place along horizontal ways or slides b,-(shown in Figs. land 2.)

Upon the under side of the head -D are secured pieces a, which correspond with those on the follower, and form between them spaces for the insertion of the bale-bands.

Below the follower is arranged a cam, E, the form of which is shown clearly in Fig. 1, and said cam is pivoted to the follower by means of a fulcrum-pin, c, inserted through the two side pieces or checks, 0, of the follower. Arranged centrally below the follower, both longitudinally and transversely thereof, is a bearing-roller, F, the journals d of which are adapted to rotate in suitable bearings provided for them, and upon which the cam E is supported; and in order tocause the cam to track properly on said roller the cam may have flanges e on each side of its face, which embrace the roller F, as seen in Fig. 3, the bearing-surface of the cam between said flanges being fiat. v

The cam E may be easily and cheaply made of wood, or of metal, if desired, and in order to render it more durable the bearing-surface between the flanges 6 may be faced with an iron band when the cam is made of wood.

The upward movement of the follower is produced by drawing the cam inward under the center of the press in a direction transverse to its fulcrum-pin c, and any suitable mechanism may be employed for the purpose. The mechanism here shown consists of a windlass or drum, G, adapted to be rotated by hand or power, and a rope, f, extending there from between the cam and its bearing-rollerF,

and secured to the cam at g. The bearingroller F has in it a circumferential groove, h, as seen in Fig. 3, which receives said rope and allows it to pass freely between said roller and the cam.

In lieu of the rope], a chain or other flexible connection might be employed.

As shown clearly in Fig. 1, the cam E is of peculiar form, and as the portion E, which has the greatest throw, is drawn upon and over the roller F, it is obvious that a small movement of the cam will produce a considerable movement of the follower. This is at a time, however, when the press-box is filled with loose material, and hence little resistance is offered to themovementof the follower; When the portion E of the cam mounts the roller F a considerable movement of the cam produces only a slight movement of the follower and a correspondingheavy pressure at the time when the follower is approaching the termination of its movement and the resistance is great.

By changing the form of the cam E the movement of the follower may be made uniform or gradually decreasing in any ratio desired relatively to the movement of the cam.

In order to make the walls of the press-box solid when the follower is in its lowest position, I provide the openings 5 i in the walls of the press-box, through which the cam works, with doors, which are automatically opened by the cam as it enters said openings. The opening t is represented as closed by a verticallysliding door, j, which has at its lower end a projection, j, on the under side of which the cam bears, and as said cam rises on the bearing-roller F it raises the door. The opening t" is closed by a vertically-hinged door, k, which may be held closed by a spring or otherwise, and which is opened by the cam striking against it in its psssage through the opening i. As fast as the Windlass G is turned backward the weight of the follower and cam, aided in the first instance by the expansion of the pressed bale, will cause the cam to move backward off the roller F and allow the follower to descend. The press-box B is closed on opposite sides by doors H, which are hinged at l, and are adapted to be opened to band the bale after it is formed and to remove the bale; and said doors are held closed by notched bars I, which project over the doors or over battens attached thereto, as seen in Fig. 2, and form catches which hold them closed. The bars I are shown as attached to one side or end of the press-box, and upon their backs is secured a piece or saddle, m, as seen in Fig. 1.

J designates a lever pivoted at n, and havingaeam-shaped head, a, which, when the lever is raised into a horizontal position, bears against the saddle m and holds the notched bars I in engagement with the doors H. When said lever is allowed to fall the notched bars are released, and the side or end of the pressbox may be sprung back enough to release the catches from the doors and allow the opening of the latter.

K designates a trip-lever, pivoted at o to the lever J, and having a projectiomp, which is adapted to rest upon a corresponding projection, a, to hold the lever J in a horizontal position, as seen in full outline in Fig. 1. When the cam E has nearly completed its movement it strikes the trip-lever K and forces it outward sufficiently to disengage the projections 11 p, whereupon the lever J will fall and the doors H be released.

The trip mechanism here represented might be greatly modified to produce the same result. If a more powerful press is desired to compress cotton already baled, two cams E may be employed in lieu of one, they being arranged in the same vertical plane, and in such case two bearing-rollers should be used, and the mechanism should be arranged to move both cams outward or inward simultaneously to produce the required movement of the follower.

By our invention we produce a simple, pow' erful, and durable press, in which the several parts may be made of wood, if desired, thus making it a very desirable machine in localities which are remote from machine-shops and foundries, and where the breakage of any part of a press, which must necessarily be made of metal, would entail great expense and loss of time.

What we claim as our invention, and desire to secure by Letters Patent, is-

1. The combination, with a press-follower, of a cam, E, pivoted thereto, a bearing-roller, F, mounted in stationary bearings below said follower, and a rope or other flexible connection, f, connected directly to said cam for drawing it upon and over said bearing-roller, and thereby raising the press-follower, substantially as specified.

The combination, with a press-follower, of a cam pivoted thereto and provided with side flanges projecting beyond its face, a bearing-roller arranged below said follower and adapted to fit between the flanges of said cam, and mechanism, substantially such as described, for drawing said cam upon and over said roller, as herein described.

3. The combination, with a press-follower, a cam pivoted thereto, and a bearing-roller for said cam, of a press-box, in the sides of which are openings through which said cam works, and doors closing said openings, and constructed and arranged to be automatically opened by said cam, substantially as specified.

. 4. The combination, with a press-follower, a cam pivoted thereto, and a bearing-roller for said cam, of a press-box in the upper part of which are doors, catches for holding said doors closed, and mechanism, substantially such as ranged to be operated by said cam, substandeseribed, upon which said cam acts at the tially as specified.- completion of its movement to release said J P DEAN catches automatically and allow said doors to Ab'uEL J ARTIN 5 be opened, substantially as specified. .h r
